Re: Small pixel camera for short focal length solar ha imaging

I've been lucky with my (recently purchased) 183mm for solar, no fixed pattern noise in Ha.

Your other option now is the zwo 533mm

Re: Baader D-ERF or Lunt ERF?

As with all etalons there is much variance between them, some are good, some not so good. It's a case of either dropping lucky when you get one or buying several before you get a good one. I did the latter.

For a refractor that size and that fast you should mount the largest one you afford internally, the bigger the better!

Re: Lunt CaK

Hi Tareq,

You really don't want to be using a reducer at all with CAK, it will only be detremental to performance. Barlows should go after the CAK module and before the camera. The best thing you will do is to stop down the aperture of your scope when imaging in CAK
